Thank you for looking.
This is a listing for a 2-way bass reflex speaker with a piezo horn and yellow cone woofer.
The manufacturer of the units is unknown, but new ones are used.

The tweeter is a horn-type piezo tweeter.
Instead of a conventional magnet-based tweeter, it uses a structure where sound is produced by distorting a piezoelectric element by applying a signal voltage to the electrodes. This type is often used in guitar amplifiers, etc.
The woofer is also new, so we believe it will become even more pleasant to listen to after aging.

It has been sanded to #320 grit and finished with linseed oil.

Double bass reflex ports on the front.
Terminals compatible with banana plugs.
Since it's a piezo tweeter, it's connected in parallel without using a network.

While carefully crafted, there may be some minor dents from the manufacturing process.
There may also be other scratches that were not noticed.

This product is not suitable for those who do not understand that it is a handmade item by an amateur, or for those who desire perfection like a manufacturer's product.

For those who prefer something different from others,
For those who like unique items,
How about a one-of-a-kind original kotospeaker?
We appreciate your consideration. m(_ _)m
